#c_lang FreeRTOS is a powerful tool for building embedded systems. It helps developers create complex systems that can do many tasks at once while using limited resources. This makes it great for small devices like those in IoT. FreeRTOS is also open-source, which means developers can modify it and share improvements. It supports many libraries and tools, such as networking and file systems, making it easy to connect devices to the internet and manage data. This helps developers quickly build and maintain their projects, saving time and effort. https://github.com/FreeRTOS/FreeRTOS

[$] Implicit arguments for BPF kfuncs Linux 内核的 kfunc 机制允许 BPF 程序直接调用内核函数。目前内核中有超过 300 个 kfunc，功能涵盖字符串处理（如 `bpf_strnlen()`）到自定义调度器（如 `scx_bpf_kick_cpu()`）等。 有时，这些 kfunc 需要访问 BPF 程序无法直接获取的上下文信息，因此无法通过参数传递。Ihor Solodrai 提交的“隐式参数”补丁集旨在解决这个问题，它允许 kfunc 隐式地接收额外的上下文参数。 原文链接：https://lwn.net/Articles/1055559/ #Linux#内核#BPF#kfunc #AIGC Read more
